I've been reading about DHCP and see that it uses limited broadcast to send its initial request to reach a DHCP server. I read about limited broadcast too which says it sends the message to every computer in the Local Area Network. A couple of questions I don't think I understand properly:
Does this mean every ordinary computer on the network is receiving this message and just ignoring this? I see a DHCP server listens on port 67 for these requests. Is it the job of a computer's firewall to be filtering out these messages that appear on port 67?
I also read about rogue DHCP servers. These would then be these computers that choose to respond to these messages rather than ignore the message?
